区域经济发展与水土资源的耦合协调研究——以辽宁省为例

Analyzing Coupled Regional Economic Development and Land- water Resource——A Case Study of Liaoning Province

在分析区域经济与资源环境耦合关系的基础上,选取指标体系构建社会经济—水资源—土地资源综合指数,建立系统协调发展度评价模型和经济发展中水土资源消耗的响应函数,以确定和识别辽宁省近十二年来水土资源经济系统的演进态势。结果表明,社会经济—水资源—土地资源系统之间的耦合协调度较低,经济发展与水土资源利用的协调关系需进一步加强。从长期来看,经济发展对水资源的依赖程度减弱,与耕地数量之间的动态效应日趋增加。

Based on the analysis of coupling relationship between regional economy and resource environment, this paper selected the index sys- tem of economic - water- land resource composite index, created a coordinated development degree evaluation model and a response function of soil and water resources consumption to economic development, to identify and characterize the evolution of land and water resources in the economic sys- tem nearly 12 years in Liaoning Province. The results were that the coordination between economic development and utilization of land and water re- sources needed to further strengthen. In the long term, the dependence of economic development on water resource was weaken, the dynamic effects of the arable land were enhanced increasingly.
